属性值的规范化处理是模糊多属性决策中首要的第一步。现有的文献只是把属性的类型分为成本型和效益型两种类型进行规范化处理。在分析6种属性类型的基础上,指出了6种属性之间的关系,并提出了一种适应6种属性类型,可以处理精确数和区间数的一种极值化数据处理方法。进一步分析了极值化处理方法的性质,通过与其它方法比较,说明了该方法计算过程简单。最后将该方法运用于绿色设计中绿色材料的选择。
The normalization of attribute values is the first major step in fuzzy multi-attribute decision making. The existing literature only divides the types of attributes into two types: cost type and benefit type. Based on the analysis of the six attribute types, the relationship between the six attributes is pointed out, and an extremal data processing method that can handle the exact numbers and the interval numbers according to six attribute types is proposed. Further analysis of the nature of the extreme value processing method, compared with other methods, shows that the method is simple calculation process. Finally, this method is applied to the selection of green materials in green design.
